As of 2015, the WHO lists red meat is a group 2A carcinogen, while processed meats, including fish and poultry, are a group 1 carcinogen on the same level of cancer causing effect as asbestos, tobacco and plutonium.
When speaking about heart disease in particular, saturated fat and cholesterol are the two most notable culprits, and the foods that are high in those and consumed the most are red meat, dairy, eggs, poultry, fish, shellfish, fried foods and refined sweets like cake and donuts.
i think the days of citing WHO as a credible medical source are long gone
